What the evidence supportsClaim scope

WorldWide Electric's HD Cast Iron competitive interchange table publishes HDRF175-L/R at 1.75 in center distance for C-face input / shaft output. Manufacturers marked by WorldWide as not dimensionally interchangeable are intentionally excluded from Replacement Intelligence. Match ratio, motor frame, shaft/bore and application ratings before ordering.

This page does say

These model numbers appear together in the cited manufacturer-published cross-reference row.
WorldWide Electric identifies HDRF175-L/R as the target model in that published row.
The source associates the row with Match installed ratio (5:1–60:1) and AGMA unit size 1.75 in center distance.

This page does not say

Every competitor model listed beside each other is independently certified as pairwise interchangeable.
Every installed accessory, bushing, motor mount, backstop, shaft, or screw-conveyor component will transfer unchanged.
The cross-reference removes the need to verify application torque, mounting, environment, and configuration.
